I will build your rust backend service


Ivan Cavlek
About this gig
I'm a senior backend/systems engineer with 10+ years of professional experience
(full time employment at companies and now my own consultancy), specializing in Rust for the last several years - production APIs, microservices, and high-throughput systems.
What I can build or fix for you:
- REST, gRPC, JSON-RPC, or WebSocket APIs in Rust (Actix-Web, Tokio ecosystem)
- New microservices, or performance/concurrency fixes in an existing Rust codebase
- Database-backed services (PostgreSQL, Redis, or NoSQL Spanner, BigTable, DynamoDB, MongoDB, ClickHouse)
- Multi-threaded / async systems where correctness and low latency both matter
- Dockerized services, ready to deploy on AWS, GCP, or DigitalOcean
- Test coverage (unit + integration) and CI/CD setup via GitHub Actions
I've shipped Rust services ranging from a newsletter platform (Actix-Web,
PostgreSQL, Redis, deployed on DigitalOcean with full CI/CD) to a custom
Ethereum-compatible node handling concurrent execution across multiple Tokio
runtimes with dedicated thread pools for low-latency read/write/execution paths.
I bring the same rigor - clean code, SOLID design, tests to a small fix as to
a full service build.
